Yes I definitely understand! I lived in Montreal for a few years and sometimes find -5C to be warm in fact. As you use Sunshine it gets to know your preferences and the language will change to reflect your climate and how you feel. Also thanks again for describing the additional information you'd like to see, we want the app to be as useful as possible so thanks!

Okay, thanks for your feedback, both the information density and forecast details. For the hourly forecasts, wind direction and speed is shown as an animation on the map view. And we incorporate wind chill and how you feel in windy conditions into the daily notifications and your tailored forecast. We will keep improving the app so thanks again for your feedback!

Both actually - the user's input of current conditions helps our forecast. We use the barometer sensor in most Android phones and iPhones to get real-time useful atmospheric data. Some other sensors available are thermometers and hygrometers, but the data is more difficult to use well.

We don't sell the user's data - user data privacy is important to us. There are lots of business models in the weather forecasting - Sunshine is much more than just an Android app. We're building a powerful weather forecast model and developing new technologies for forecasting! We're currently VC funded and will be developing our business model as we grow.

Yes, Sunshine does take that into account! As you send in the weather conditions and how it feels, it uses the temperature, place, time of year, time of day, etc, to build your preferences. So in future forecasts, the app learns how you prefer the weather even accounting for seasonal changes!

Thanks for your kind words, and great question. We'll be expanding to more countries in the future and probably yours too!

This is a fantastic historical account that I never knew anything about. Having ready Tolstoy (but never Gorky) it is really enlightening and it's a great read - and much of it is relevant to our society today.

Welcome to the app and thanks so much! We're really glad you like the notifications - and we're always improving both the notifications and the app itself! It means a lot to us that you love it, so thanks again!

We get our raw weather data from a variety of sources - I'm not actually sure of the list (not on that team) but I know we source from a few different places. One of our new major data sources is the sensor data from phones themselves!

We input that sourced data into our weather models that we run on our servers and process the results back to our users. There is an additional layer that we run after the generic forecasts are generated that customizes the response for each user, so that your weather information is based not only on how the forecast ran but also your personal preferences.

Yes it does forecast the weather and get it right! We offer hourly forecasts for the next day ahead, and then daily summaries for the next 3 days.

We run our own weather forecasts, using data from both existing sources like NOAA, and also the crowdsourced barometric pressure data and other sensor data from smartphones. We do this to have more accurate and more real-time ground-truth data where our users actually are (rather than just where weather stations are).

As a side note, we also have better results for conditions when you look out the window! Something I've always been annoyed by is when Google or some other provider will tell you that it's currently cloudy outside, but actually it's sunny! That happens to be almost daily with other services - and our community fixes this by reporting the current conditions outside. Another effect of having better current conditions is that we can seed our weather models with more accurate current conditions, which helps with the forecast accuracy as well!

We're very interested in launching in Europe, so stay tuned for that in the future! No bot accounts in Sunshine, just lots of real people submitting weather reports and participating in the community! Thanks for your feedback and I can't wait for us to launch in Poland!

We weren't aware of the udacity courses when we named it Sunshine! And no, we don't really expect much confusion between our app and the other apps - they are very different!

Sunshine is a big community of people, and a totally new kind of app. We run our own weather forecasts, we build apps across platforms to deliver the best weather notifications we can, and we tailor it for each of our users.

The other apps out there typically use weather data from an already-existing data source (do they all use the same source?) and are actually very different apps compared to Sunshine! We deliver tailored notifications based on you training the app - and we make it the best for you each day.

If we haven't launched in your country, then the behavior is unpredictable since we don't support full global weather forecasts yet, or geocoders, etc. I'm not sure I fully understand what you experienced, but I can say that we don't do anything misleading like you're suggesting. The Sunshine users are real users in real places!

Also note that many Sunshiners travel a lot, sometimes I notice someone who normally reports from Florida is now in California or in New York - that happens lots actually.

So I'm not sure what could have caused the thing you're describing, but since we don't support your country yet, it could have been any number of things.

What country do you live in, by the way? We will be expanding to more countries as we grow!
